. REFRIGERATEUR.

` Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvementsin Refrigerators,of which thefollowing is a specification. l

My invention relates to improvements in refrigerators, and more particularly to an improved cold storage apparatus, designed primarily for the kee ing of meats in meat stores, and which willpeconomize ice and secure a temperature below freezing to form ice of its own.

A further object is to provide'improve ments of this character with a series of cylindrical tanks to contain cracked ice and brine, which will cause a frost or ice covering to forni aroundthe outside 0f the tanks and reduce the temperature in the refrigerator to as low a point as may be desired.

A further object is to provide improvements of this characterwith improved means for agitating or stirring the interior of the said tanks, improved means for draining thetanks and provide an improved pickling tank in which all of the first mentioned tanks are located to receive the low temperature from said tanks, as well as from ice and 'brine contained'in the pickling tank.

-With these and other objects in view, the invention consists in certain novel features yof construction, and combinations and arrangements of parts as will bemore fully hereinafter described and pointed out in the claims. A

In theaccompanying drawings, Figure 1, is a perspective view illustrating my improvements. Fig. 2 'is a fragmentary view in section through the wall of the apparatus.

I Fig. 3, is a view 1n vertical longitudinal section.4 Fig 4, is a view in horizontal cross section. Fig. 5, isa view similar to Fig. 3, but .taken at a point nearer the front of the refrigerator, and Fig. 6, is a view in vertical cross section. 1 l represents the casing or boxing of my improved refrigerator, which is made preferably of two thicknesses ofwood, with a filling of paper or other insulating sheeting as shownin Fig. 2, to reduce the interchange of temperatures between the Vinterior in ythe refrigerator and outside air to a minimum. The refrigerator is divided by a horizontal Specification of Letters Patent. Patented`,]a,n 11, 1910, Application med irebnuan';k 17, y190e. serial No. 478,372.

partition 2, into' a small upper compartment 3, and the lower main compartment 4. Ac-

cess to this upper compartmentV is had.

vand may be of any desired form, having transparent or opaque panes asjmay be desired.

Secured the receptacle at a point removed from the bottom thereof, and extending longitudinally throughout the refrigerator, is a board or timber 7, and a rectangular metal tank 8 is located on the bottom of the refrigerator, and extends from the front of the refrigerator backward to the rear edge ofthe said board or timber 7, and consti-y tutes a pickling tank as will hereafter appear. y

Tl1e board or timber 7 and the partition 2 are provided with: alined circular openings in which cylindrical tanks 9 are supported. I have illustrated five of these tanks, but of course am not limited in their number.

' 'lhese tanks are adapted to contain cracked ice and brine, and are each drained through a common pipe 10, which projects outside of the refrigerator, and is provided with a drain cock 1l. In` all of these tanks I provide rotary stirrers or agitators 12, which latter comprise a central rod or shaft 13, having a thrust bearing 14 in the bottom of the tank, and made angular'at its upper end, which projects through the removable cap or closure 15 at the top of the tank and intothe compartment 3, so that an instrument can be readilyinserted into the compartment 3 to turn the stirrers and agitate the contents of the tanks The stirrers may of course, be made in yvarious ways, but I have illustrated one 'form in which the stirrers comprise blades to extend approximately throughout the length of the tankand connected to the be hung in the compartment, but I of course do not limit myself to any particular manner of supporting the meat.

The tank 8 as above described is intended as a pickling tank, and is adapted to contain ice and brine up to the desired level, and to 'receive the meat to be lpickled in cans or receptacles 19, and removable covers 20, close the upper ends of the tanks to keep AZout the interior space of the refrigerator may of course be utilized in various ways for refrigerating urposes. y

In operation all of the tanks 9 are filled with cracked ice and'brine, and almost imfmediately frost will begin to form around the tanks, and the longer the device'is in use, the thicker and heavier will become the coating of ice around the outside of the tanks, reducing the temperature in the refrigerator as low as it is safe to keep the meats. brine to the desired level, and by regulatin the quantities of ice and brine in the severa tanks, the temperatureucan be regulated to exactly suit conditions.

It witl be understood that the connection between the' bar or timber 7 and partition 2 and the several tanks 9, is an approximately air tight juncture, and when the covers 20, which are also approximately air ti ht, are in position, there are three chambers ormed, whichv are for all practical purposes air tight with relation to eachother, so as to Yprevent an interchange of temperatures, and allow free access to the intermediate chamber where the meat and other articles are stored without affecting, to any appreciable extent, the temperature of the brine tank below, and access may be had to the upper ends of the tanks 9 to charge them without a'ecting the temperatures of eitherof the chambers below.

Various slight changes might be made in the general form and arrangement of parts I described without departing from my invention, and hence I do not restrict myself v and adapted to be supplied with a refriger- The tank 8 is also to contain ice ,and

to the precise details set forth, but consider myself at libert to make such changes and alterations as airly fall Within the spirit and scope of the claims.-

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a refrigerator, the combinationwith a box or casin of two approximately airtight horizonta partitions dividing said box or casing into a lowerbrine tank or chamber, an intermediate refri erating chamber, and upper feeding cham er, oneormore tanks proJecting into all of said chambers ant through said feeding chamber.

2. In a refrigerator, the combination with a box or casing, of two horizontal partitions in said casing having registering openings and forming an uppervfeeding chamber, a ower brine tank or chamber, and an intermediate provision chamber, refrigerant tanks located in saidv registered openings, said partitions normally preventing any circulation of air between the chambers, said refrigerant tanks passing through the intermediate chamber and projecting into the upper and lower chambers, and being provlded with removable covers in the upper chamber.

3. In a refrigerator, the combination with a box or casing, of a horizontal partition spaced from the top of the casing and preventing circulationl of air between the up er chamber yformed thereby and Vthe cham er below, a brinel tank in the bottom of the box or casing, an approximately air ti ht partition above said brine tank, remova le covers in said last mentioned partition, and refrigerant tanks projecting through both of said chambers and intopthe brine tank.

In testimony whereof I have si ed my name to this specification in the presence of two subscribing witnesses. f
